Although the maker is unknown, it is very similar to a number of patterns called "Shell" that were made by virtually all the more important silver manufacturers at the time (Gorham in 1890; Reed & Barton in 1900; Towle in 1889; Frank Smith in 1890; Mt. Vernon in 1865; and Lunt in 1888). It appears most similar to Frank Smith's version, but would work nicely with any of these or other Colonial Revival patterns.
Excellent condition. 8.5" long.
One glass has a flake at the bottom edge (see photo) and two pinpoint roughnesses along the top rim. Another has a couple of pinpoint roughnesses underneath the bottom edge (not noticeable from the top).
These are certainly among the finest cocktail glasses we've seen and would look great with a classic cocktail shaker featuring a rooster motif.
Origin: Germany, ca. 1920. Condition: Light glaze crazing; a small chip on the cap and three small flakes at the bottom edge are visible in the photos (all could be easily repaired). Size: 9-1/2" tall.
